xrandr 1600x900 but has boarders around screen i965 intel

[francisuk1989]

I have a HP S2031a 20" LCD Monitor (Widescreen 16:9) and using VGA and i have tried adding custom resolution with xrandr as the following:

cvt 1600 900
# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz

xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync

xrandr --addmode VGA-1 "1600x900_60.00

however is working OK and has made the screen bigger but has a black boarder around with missing display screen (also to add it has a very thin line at the very right of the screen just like if is been cracked what it hasn't in this case.)

how can i resolve this issue as on Windows is display fine!

If you had something other than VGA to connect it with, I'd start there. Otherwise, you'll have to work on your modeline. You can adjust it to change the scan, like this example to correct overscan:

Modeline "1600x900" 127.84 1600 1696 1872 2208 900 901 904 965 -HSync +Vsync
